CAR COUPLING.

SPECIFICATION forming part of Letters Patent No. 385,505, dated July 3,1888.

Application filed January 14, 1888. Serial No. 260,774. (No model.)

To CLZZ whom it may concern:

Be it known that I, CONOVER R. Coon, a citizen of the United States,residing at Yorkville', in-the'county of Kendall and State of Illinois,have invented a new and useful In1 provement in OarOouplings, of whichthe following is a specification.

My invention relates to improvements in car-couplings, and it has forits object to provide an automatic coupler which is simple and easilyoperated and in which the link is guided to its place in the draw-headby improved means.

The invention consists in a certain novel construction and combinationof devices,which is hereinafter more fully set forth in connectioh withthe accompanying drawings, wherein- Figure l is a side View of twocouplers connected. Fig. 2 is a longitudinal central section of thesame. Fig. 3 is a front view of one of the couplers. Fig. 4 is a detailperspective view .of the link.

Referring by letter to the drawings, A designates the draw-head,which isprovided with a recess, B. This recess is tapered or funnelshaped inform and its mouth is elliptical in shape, with the major diameter ofthe ellipse in a vertical position.

Aligned openings 0 O are formed in the upper and lower sides of thedrawhead near its mouth, and the upper opening O, is elon gated in shapeand is grooved "or corrugated, for a purpose to be explainedhereinafter.

The sides of the draw-head are provided with lateral ears D D, which areprovided with aligned apertures d d, in which are dis posed theremovable pins E E. On these pins are adapted to be hung the links whichare not in use in thevdraw-head, it being desirable under certaincircumstances to carry one or two extra links for an emergency, and inthis way they are always within reach and cannot become lost.

F represents an extra link, which is en gaged by one of the pins. Thecoupling-pin G is curved slightly, and when its lower end is engaged inthe upper opening, 0, the pin is held in an elevated dotted lines inFig. 2.

position, as shown in The link H is provided at each end with a taperedhead, I, which is reduced to a point. It will be seen that if the saidpoint of the head strikes within the edge of the mouth of the recess theend of the link will be guided by the tapered head,sliding on the sidesof the tapered or funnel-shaped recess to its proper position.

The coupling-pin is arranged so that its lower end projects slightly(say about one inch or more) below the upper side of the tapered recessin the draw-head, so that when the link enters the said recess itstrikes the projecting end of the pin, thereby tripping it and causingit to fall and engage in the opening 0. As the pin falls it passesthrough the longitudinal slot of the link, and thus secures the latterin the draw-head and completes the coupling.

The device, as will be seen from the foregoing description, is simple,and the parts are so arranged that they are not only strong and durable,but operate very effectively.

\Vhen the recess in the draw-head and the ends of the link are shaped asherein described, there is no danger of the link failing to properlyenter the draw-head.

I claim- 1. In a car-coupling, the combination of the draw-head havingthe openings 0 O in its upper and lower sides, the upper opening beingcorrugated, the pin engaging at its lower end in the upper opening whenin its elevated position, and the link adapted to trip the pin when itenters the draw-head to cause it to fall, substantially as specified.

2. In a car-coupling, the combination of the draw-head having theelongated and rough ened opening 0 in its upperside and the opening G inits lower side, and the pin to engage in the said openings,substantially as specified.

3. In acar-coupling, the combination of the draw-head having the lateralapertured ears D, the removable pins engaged in the apertures, and thecoupling-link adapted to be engaged by one of the said pins when not inuse, substantially as and for the purpose specified.

4. In a car-coupling, the combination of the draw-head having thetapered or funnel-shaped recess B therein and the aligned openings 0 Cin its upper and lower sides, the curved In testimony thatI claim theforegoing as my coupling-pin adapted when in the elevated own I havehereto affixed my signature in IO position to be engaged in the upperopening, presence of two Witnesses,

O, and project sli 'htly below the upper side of the recess B, 53a thecoupling-link having CONOVEP K the tapered heads I I on its oppositeends, all Witnesses: constructed and arranged substantially as andWILLIAM H. HoPKINs, for the purpose specified. GEO, ELLIOTT.
